Introduction
About DiskGenius
DiskGenius is highly-efficient tool for data recovery, partition management and data
backup. It is designed with convenient user-interface and effective features, which
makes it easy to manage disk space, recover deleted files, clone partition, image
disk, etc.
Technical Specification
Recommended Hardware requirement: 1 GHz x86 or compatible CPU, 512mb RAM
memory, mouse and keyboard
Supported file system: FAT, FAT32, exFAT, NTFS, EXT2, EXT3, EXT4
Supported operating system: Windows 2000/XP/Vista/7/8/8.1/10, Small Business
Server 2011/2003/2008, Windows home server 2011, and Windows Server
2003/2008/2012/2016 (both 32bit and 64bit).

Partition Management
Create New Partition
You should decide partition type before creating new partition table. There are three
types of partitions, primary partition, extended partition and logical partition. Primary
partition is created on hard drive directly, which is generally used to install and boot
operating system. Due to the limitation on MBR partition table, there can be 4
primary partitions at most, or 3 primary partitions and 1 extended partition.
Extended partition is a kind of special primary partition, and it can contain several

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 6
logical partitions. Logical partition is created on extended partition, and the number
of logical partitions is not limited.
1. Create new partition on free disk space
Step 1 Select free disk space on hard drive and click New Partition button from
toolbar and Create New Partition window will pop up.

Step 2 Select partition type, file system and partition size and click OK button.
To make sure the partition is 4K aligned you can select option "Align to Integral
Multiple of Sectors".

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 7
Note: You can click Advanced button to set more parameters for the partition, as
follows:

You can set partition's beginning and ending cylinder, beginning sectors and sector
numbers. As to GUID partition table, more partition settings are available.
Step 3 Click Save All button to save the partition to partition table and format the
partition.
The newly created partition is not saved to hard drive immediately, as it is created in
memory for the moment. Thus, you need to save the partition to partition table
manually before you can see it in Windows Explorer. Such approach is to prevent
data loss caused by improper operation.
2. Create new partition on existing partition
DiskGenius is able to create a partition on existing partition by splitting one partition
into two without data loss.

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 8
Step 1 Right-click on a partition and select Create New Partition from context
menu.

Step 2 Enter partition size for these two partitions and click Start button.

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 9


Active Partition (Mark Partition as Active)
An active partition is a primary partition on a hard drive set as the bootable partition
that contains operating system. Only one partition on each hard drive can be set as
an active partition.
To active a partition, please right-click on the primary partition and select "Mark
Partition As Active" from context menu.

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 10

If you want to remove Active mark for the partition, you can right-click on it and
select "Remove Partition's Active Mark", as follows:

EXT2, EXT3 and EXT4 file system.
Step 1 Select the partition you want to format and click Format button from
toolbar, or right-click on the partition to choose Format Current Partition.

Step 2 Select file system, cluster size, volume label and click Format button.
Also, you can select "Surface Scan" which will scan the drive for bad sectors during
formatting. However, surface scan takes long time and there is no need to do so on
most new hard drives.

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 14
As to NTFS partition, you can select Enable Compression to enable NTFS file system's
data compression feature.
If the partition to be formatted is primary partition and file system is set as FAT32,
FAT16 or FAT12, the option "Create DOS system" will be available. If it is selected,
the formatting process will create a DOS system in this partition, which can be used
to boot computer.
Step 3 Click Yes when DiskGenius asks confirmation for the operation, and the
partition will be formatted quickly.



Hide Partition
Hide partition
A hidden partition does not have a drive letter and it cannot be seen in Windows
Explorer, thus operating systems cannot access it. Files in hidden partition are not
lost, but they cannot be accessed in normal method.

enter DOS version to complete the task. If your operating system does not support
DOS system anymore, you can enter DiskGenius WinPE version to resize system
partition.
Please do not access the partition being resized in case of any unexpected issues.
The resizing process may take long time if there are too many files on the partition.
In that case, you can set operations after resizing finishes.

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 22
Partition resizing may fail to complete or even cause data loss due to hard drive or
partition errors, bad sectors, sudden power failure or system errors. Thus, resizing
partition is a risky action to some extent and data backup is necessary.

Partition Backup
Partition backup is able to back up all data and settings of a partition into a specified
file which is usually called image file. With the backup file, you can restore partition
when the partition gets damaged or data gets lost. DiskGenius provides three ways
to backup partition.
Sector-by-sector backup: It allows you to create an image of all sectors on the
selected partition, including sectors with data and blank sectors. Therefore, the
process may take longer time than normal partition backup. The image file can be
restored to source partition or other partition which has the exact same size.
Backup partition by data storage structure: Back up valid data of the source
partition by file system structure to the image file without any changes. Sine this
mode only backs up valid data and it is the fasted. However, when you restore data
from image file, the destination partition should have the same size as the source
partition.
Backup partition by file: Backs up all files and other valid data of source partition
to image file, which does not backup invalid data and takes shorter time. The image
file can be restored to any partition whose capacity is able store these files. Files
restored from image file will be reorganized and there won't be file fragments.
The backup file can be compressed and you can set compression level from Fast,
Normal and High Quality. In general, image file with higher compression level is in
smaller size but takes longer time. In most cases, Fast is the default and best choice.
Backup type: Full backup and incremental backup.
Full back up: Backs up all data no matter whether there is a backup.
Incremental backup: Only backs up changed data or content.

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 35

Clone Partition (Copy Partition)
Cloning partition is the process that copies content of one partition on the disk to
another partition without any data loss. The destination partition will be loaded with
same data as the source partition. DiskGenius provides three ways of cloning
partition:
Clone partition sector by sector: A sector-by-sector partition cloning ensures the
destination partition is exactly the same as source partition, as it copies all sectors of

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 47
source partition, including used sectors, blank sectors and bad sectors. The target
partition should be equal in size to the partition being cloned.
Copy all valid sectors according to the layout of the file system: This
partition cloning method copies all valid data of source partition to destination
volume in line with the layout of data organization structure. The cloning process
excludes invalid data but does not reorganize data. It is the fasted cloning method.
The destination partition and source partition should be in the same size.
Clone partition by files: Copies all files from source partition to destination
partition by analyzing data organizing structure. Files in destination partition will be
reorganized and there won't be fragments. The cloning works as long as destination
partition is able to hold files to be cloned in source partition.
Step 1 Select the partition you want to clone and click Tools -> Clone Partition.

Recover Deleted or Lost Files (File Recovery)
This feature can be used to recover deleted, lost or formatted files from any storage
devices which are formatted as NTFS, exFAT, FAT32, FAT16, FAT12, Ext2, Ext3 and
Ext4 file system. The recovery process is read-only and does not write any data to
original device. Note: if you want to recover lost or deleted partitions, please refer to
lost partition recovery.
Recover deleted files
Step 1 Select the partition where deleted files were stored and click File Recovery
button from toolbar to open Recover Files window.

In some cases, deleted files cannot be recovered even though they are deleted just
for a while. That's because vital data information of deleted files has been destroyed
by operating system or users' improper operations. Such operations are usually
generated inadvertently, for example, some user continues accessing or editing files
in Windows Explorer, which usually causes large amount of cache files. Such
operations are able to destroy virtual information to successful file recovery. On this
occasion, it is necessary to search for lost files by file type. Though files recovered in
this way are named by numbers, users can preview files to identify file content.
Step 3 Preview and filter recoverable files.

clones data for each partition. Partitions created on destination disk are identical to
those on original disk. There are three disk cloning modes available:
Copy all sectors: Copy all sectors of the disk to destination disk without considering
whether sectors are in use or not. This clone mode may copy a large amount of
invalid data and takes longer time. However, it is the most complete copy method
which can copy all the data of the source disk to the target disk.
Copy all valid sectors according to the layout of the file system: Copy all
valid data of the source disk to corresponding partitions on the destination disk in
line with the layout of the file system. Data structure on destination partition will be
exactly the same as source partition. Cloning process gets rid of invalid sector, so it
is quite fast.
Copy all files: Copy all the data of source disk to destination disk by analyzing file
system layout of the source disk. When copying data, files will be rearranged
according to file system layout. There won't be file fragments and it is very fast.
Note:

EASSOS Technology Co., Ltd. https://www.diskgenius.com/ 89
If the disk to be cloned contains partition whose file system is not supported by the
